Exploring the Southern Hemisphere: Plant Bug Planetary Biodiversity Inventory Field Work in Australia and South Africa presented by Randall T. Schuh Curator and Chair Division of Invertebrate Zoology American Museum of Natural History, New York
2
Planetary Biodiversity Inventories Funding: US National Science Foundation, 2003 Criteria: Worldwide and monophyletic taxa Duration: 5 years Projects: Eumycetozoa (slime molds): 1000 species Solanum (Solanaceae): 1500 species Miridae (Heteroptera): 5000 species Siluriformes (cat fishes): 2500 species http://research.amnh.org/pbi

PBI Participants
5
7 infraorders 85 families 40,000 species described Heteroptera: True Bugs
7
Infraorder: Cimicomorpha 1,350 valid genera 10,200 valid species mostly phytophagous high host specificity many myrmecomorphic some aposematic Miridae: Plant Bugs
8
Status as of 2003 8 recognized tribes 485 described genera 3900 described species ~ 1400 published hosts ~ 90 new genera ~ 1200 new species in collections PBI Target Taxa: Orthotylinae and Phylinae
9
Exemplar Orthotylinae and Phylinae
10
Application of taxon focused techniques Maximize discovery of new taxa Extend geographic coverage Maximize host/biological information Maximize specimen quality Maximize specimen numbers Field Work Fundamentals

19
Extreme plant diversity and endemism Unique biotic affinities Limited prior sampling Few publications and described taxa Unstudied by classical & modern authors No local specialists SOUTH AFRICAN FIELD WORK Western Cape as a PBI target area: Namaqualand–Little Karoo–Fynbos
